HEEL BASE.

Application led March 7,

This invention relates to heel bases, mean v separately applied to the shoe to provide Y a level surface on which a heel body or lift of rubber, leather or other material may be applied and secured; or they may be combined with other elements to form a complete heel prior to attachment to a shoe. I-Ience for the purpose of this specification the definition of heel base includes not only a dis tinct article consisting of a single complete lift, or a few of such lifts, and an attached rand, but also that part of an entire heel which comprises the base partv of the heel and is composed of the ,rand and the.y next adjacent complete lift or lifts.

The object of the invention is to make available for use in the manufacture of such heel bases gougings and skivings of leather resulting from the manufacture of shoev parts and constitutingr waste which 'has' no value except the nominal value of raw material for leather-board manufacture. In pursuance of this object I take the gougings which are formed in the course of cutting a cup in the seating face of an all leather heel, and the skivings from leather counter stiffeners, and combine such gougings and skivings into associated lifts and rands forming merchantable heel bases. In doing so I effect important economies in the manufacture of heel bases and convert relatively valueless scrap into valuable merchandise.

I will now more particularly describe the characteristics of the invention with reference to the drawings in which,-

It is a common practice in the manufacture of high grade leather heels to form a depression in one face by gouging out thispart of the heel, and then building up the edges of the concavity so formedl by adding a rand to lform the so-called cup of the heel which adapts it to the convex heel seat of a shoe. The pieces removed by this practice are what I refer to as gougings in this specification. They have approximately the same outline and lateral dimensions as the heels from which they are cut, since the gouging operation is so performed as to remove practically all of the face of the heel within its perimeter,

and areof varying thickness, tapering from a thin edge at all of perimeter except the breast end and hav-ing their greatest thick- Such a gouging is The heels on ness in the middle area. n shown at a in the drawings.

which this practice is performed are usually all leather heels.

shoe factories and fit only'to be ground up orl shreddedfand made into leather-board.

I take such gougings, of the dimensions suitable for the sizes of heel bases I am mak-v ing, and combine them with rands b, taking in each case a rand (single or composite) which has a height or thickness at the outer edge equal to the required height of the finished heelbase. The rand is. laid on the tapered edge zone of the gouging and cemented thereto, or otherwise secured in any suitable manner. Cement is indicated in the drawings by stippling.

Preferably I `make the 'rand of several strips of leather Wedge shaped in cross section. In the form of the invention shown in The gougings resultingv from this practice, even though com-posed of.

lll).

Figs. l, 2 and 3, three of such strips are used,

.'designated, respectively, '29, b and b2. The

tapered edges of the gouging require the rand to be made of greater height at the outer-edge than those used with lifts of uniform thickness in building heel bases, and this fact en ables me to effect a further economy by using a narrow wedge strip 7/ between two wide strips and b2, and thus to utilize narrower skivings from the counter stiffeners of shoes, which have heretofore been useless for any purpose and have been thrown in with the scrap to be made into leather-board. The wider skivings from counter stifleners have heretofore been used for making rands, but only those skivings have been suitable for that purpose which are wide enough to cross the locations in which nails are driven to fasten the heel to the shoe, and those which are so narrow as not to be penetrated and held by such nails have not been suitable for making rands. I use as the rand to be combined with a gouging in my new heel base, two strips, b and b2,having suficient width for the purpose as above explained, and an intel'- mediate strip Z2 which is not wide enough in itself to serve as a rand, but is placed between the widerA strips and is so firmly gripped between them, as well as being bonded to them by cement, as to be securely retainedy in place, when the heel base is made fast to the shoe, by the attaching nails which pass through the wider rand strips. These strips are preferably all assembled together into the composi ite rand, shown by itself in Fig. 3, before being applied to the lift formed by the heel gouging a, although they may be built up on the gouging.

Inthe construction above described, the

heel gouging lift has approximately the external form and dimensions required of the finished heelbase, or may have some excess to be trimmed olf. But I am not necessarily restricted to the use of agouging so long and wide as this, for the rand may be placed so as to extend beyond its edges. In Figs. 5 9, I have shown how gougings smaller than the finished heel base may be effectively used to make a composite lift of required areav having substantial thickness at its edges. In making such lifts VI take a gouging a and extend it at the sides andV back by tapered pieces c, (Z and c, which are cut from heel gougings of similar character in such inanner that segments of the outline of the heel base are cut in the thick portions of the gougings. The pieces c and d which build out the sides of the piece a are so cut that one end coincides with the breast end of the gouging from which it is cut, while the opposite end tapers off to nothing. These pieces are laid so as to overlap the gouging a, withtheir thick ends ycoinciding with the breast end of the piece a and their thick convex sides conforming to the shape of the finished heel base.

The piece e, by which the back or rear end of the composite lift is extended, is cut so that its outline which conforms to the curvature of the rear end of the heel lies in the thick partfof a heel gouging and its opposite edge, and both ends, are tapered to no thickness. rI`he parts of these pieces and the center From one point of view the pieces c, d ande are parts of a rand, since they cooperate with the strips b and b to form a complete rand and build up the edges of the heel base to the required height essentially the same as the rand strip b2, previously described. But in another aspect they are also parts of a' lift, since they also build out the gouging a to the required peripheral dimension and cooperatel withthe latter in forming a complete lift. l/Vhile the lift so constituted is a constituent part of the complete heel base, and is claimed as such, nevertheless I do not limit my claim to protection for such lift to its use in this combination only, but I claim it also as a pieced lift available for all uses to which such a lift may be put.

It will be apparent from the foregoing eX- planation that by the present invention I have created a new utility for scraps from two differentl sources which `have heretofore been only waste.

Although I have described the scraps thus utilized as being leather scraps, it is to be understood that I have not intended to limitv my invention in respect to material, for I may use the gougings and skivings from heels and counters of any material. That is', the gougings and skivings are made of the same Inaterial as the pieces from which they are cut.

The heel base thus described, alo'ne or combined with additional lifts, may be subjected to the compressing operation usual in the manufacture of heels, whereby the material is compacted and made more dense, the cup or concavity bounded by the rand is given the required contour, 'determined by the form of the die which engages that face of the base in the compressing operation, and the opposite face of the heel base is made flat and level.

Vhat I claim and 'desire to secure by Letters Patent is:

1. A heel base consisting of a lift made of a heel gouging and a rand formed in partof a skiving, too narrow to serve by itself as a rand, interposed between and gripped by two other Vrand pieces of suiicient width.`

2. A heel base comprising a lift formed of a heel 'gouging and a rand having suicient height at its out-er e-dge to compensate for the beveled formation of such lift.

3. A composite heel lift consisting of a heel gouging and pieces of other gougings laid with their thin edges overlapping the thin edges of the first named gougings at the opposite sides and at the rear thereof and cut on the outline and to the dimensions of a prescribed heel lift.

4. A pieced heel lift consisting of a heel gouging having a relatively thick central part and thin edges and edge pieces extending said 2:. gouging peripherally to a given outline and a greater thickness, said edge pieces being each a fragment of a heel gouging cut through the thickest part of such gouging on an outline conforming to a segment of the periphery of the given heel lift outline and laid with its part of diminishing thickness overlapping the beveled edge part of the first named gouging.

5. A heel base composed of the lift set forth in claim 4, a rand strip formed of a narrow counter skiving laid upon sai-d extension edge pieces .with its thicker edge in substantial peripheral conformity therewith, and a wider rand strip overlying the preceding rand strip in similar peripheral conformity therewith;

all of the pieces herein specified being bonded adhesively to one another.

In testimony whereof I have affixed my signature.
